Application led February 16, 17925. Serial No. 9,635.

The invention relates t'o refrigerating apparatus of that type designed for small house plants and has more particular reference to the construction of the detachable cover for the ice tray compartment. It is usual with such installations to provide within the brine tank a compartment for the reception of trays in which fresh water can be frozen. This compartment is usually surrounded by the brine, but is o en at the front for the insertion and with rawal of the trays, being temporarily closed by a detachable door or cover. It has been found, however, that this cover'or door will freeze to -the tank, due to the collection of condensed vapor so that it is difficult to open the compartment.

This frequently results in the use of some tool, such for instance as an ice pick, which may cause a puncturing of the tankgor other 4injury to the apparatus.

It is the object of the present invention to provide a detachable cover or closure for this compartment which is easily removed without danger of freezing and. which also forms an effective closure for preventing air circulation in and out of the compartment. To this end the invention consists in the construction as hereinafter set forth.

In the drawings:

Figure 1 is a front elevation of the brine tank showing the improved closure for the ice tray compartment;

Figure 2 is a vertical Section therethrough.

A'is the brine tank of a refrigerating apparatus of any suitable construction and B is the compartment within said tank for receiving the ice trays. or closure for the opening into the compartment B and which is of the following construction:

The cover is preferably formed of sheet metal and is provided with an inwardly projecting annular flange D for completely surrounding the compartment B and contacting with its edge against the'wall of the brine tank. At the top of the compartment B there is the upwardly and outwardly inclined lug or hook E, which is engageable with an aperture in the cover C. The arrangement is such that when the cover is hung upon the hook E, the inclination of the latter will move the top portion of the flange D in contact with the wall of the brine tank and at the same time gravity will force the lower portion of said flange into close contact therewith, thus producing a t-ightclosure.

C is the detachable cover` There is not, however, any danger of this flange freezing to the tank, for the fact that the cover is outwardly offset exposes it to the circulating air and keeps the temperature above the freezing point; also the amount of surface in contact with the wall of the tank ,is so slight that there would be little adhesion even in case of freezing.

The cover C is preferably provided with a suitable handle F by means of which it can be easily lifted off from the hook E or replaced thereon.

What I claim as my invention is:

l. The combination with a casing having a freezing chamber therein opening out through a substantially vertical wall of the tank, of a-closure for said chamber comprising a cover having an inwardly extending annular flange surrounding the opening into said chamber and forming a limited contact with the walls of the casing, and means for supporting said closure and holding said flange in contact. 2. The combinationwith a brine tank having a freezing chamber thereinr opening out through a vertical wall of the tank, of a closure for said chamber comprising a 'cover plate having an inwardly extending annular flange surrounding the opening and forming a limited contact with the wall of the tank, and means for supporting said cover with said flangeheld in contact. 3. The combination with a brine tank having a freezing chamber therein opening out through a vertical wall of the tank, of a closure for said chamber comprising a cover plate having an inwardly extending flange surroundingsaid opening and having edge contact with the wall of the tank, and a suspension'hook for said cover supporting the same with said flange held in contact.' 4. The combination with a brine tank having a freezingl chamber therein opening out through afve'rtical wall of said tank, of a closure for said opening comprising a cover plate normally in the plane o'set from the plane of the tank and provided with an inwardly extending annular flange surrounding the opening and having edge contact with the tank, and an inclined supporting hook engaging the upper end of said cover for holding said flange in contact with said tank.

5. The combination with a casing having a freezing'chamber therein, of a closure for said chamber comprising a cover having an aperture at its upper end and having 4a lateral fiange surrounding the opening into said chamber, and a hook secured to said casing above the chamber and having an upwardly and outwardly inclined portion engaging the aperture in said cover and holding the lateral fiange aforesaid against said chamber.

6. The combination with a casing having a 'freezing chamber therein opening out through a substantially vertical wall of the casing, of a closure for said chamber comprising a cover havin inwardly extending flanges surrounding the opening into said chamber and forming a limited contact with the walls of said casing, and means for supporting said closure so that the flanges aforesaid will be in edge contact with the vertical wall aforesaid when said closure is in closed position.

7. The combination with a casing having a freezing chamber therein opening out through a substantially vertical wall of said casing, of a closure for said chamber comprising a cover having flanges projecting at substantially right angles from said cover for edge contact with the vertical wall aforesaid of said casing. and supporting means for said cover upon the front wall of said casing including means for permitting said cover to swing outwardly with respect to said vertical wall and to swing -inwardly with respect to said wall so that the edges of said flanges will be in contact with the said Vertical wall.

l8. The combination with a casing having a lfreezing chamber therein opening out through a substantially vertical wall of the tank, of a closure for said chamber comprising a cover having an inwardly extending annular flange surrounding the opening into said chamber and forming a limited contact with the walls of the casing, and means for supporting said closure and holding said flange in contact.

In testimony whereof I affix my signature.
